House Committee Drastically Reduces SRF Budgets For Next Year
The problem with sulfur in gasoline is that it degrades the effectiveness of a car's catalytic converter. The EPA proposed two options. The first maintains both the current 80 parts per million (ppm) refinery gate sulfur cap and 95-ppm downstream sulfur cap. Under the second approach, the refinery gate cap would be reduced to 50 ppm and the downstream cap would be reduced to 65 ppm.
